Abstract

The invention relates to a wireless vehicle detector which comprises a controller, a sensor, a power supply and at least one RF (radio frequency) communication module. The detector is characterized in that the sensor is connected with the controller through a signal wire; and the controller controls the on and off of the power supply through a signal of the sensor. The invention also provides three methods of turning on and off the wireless vehicle detector by using an acceleration transducer or a magsensor, a sensor signal is skillfully used for controlling the on and off of the wireless vehicle detector, the mechanisms such as a button and the like are not needed to be arranged on the shell of the wireless vehicle detector to connect internal electronic components, so as to maintain the high tightness and resistance to pressure of the wireless vehicle detector, and realize the on-and-off actions of the wireless vehicle detector conveniently.

Description

technical field [0001] The invention relates to the field of vehicle detection, in particular to a wireless vehicle detector and a speed measuring method thereof. Background technique [0002] Vehicle detectors are usually used in multiple intelligent transportation systems such as intelligent signal light control systems, traffic flow detection systems, electronic police systems, urban entrance and exit management, and urban traffic guidance systems to detect the presence and speed of vehicles. [0003] The traditional ground induction coil vehicle detector detects the vehicle by digging a wire slot on the road surface and winding a coil inside, and the data is then excavated and the wire slot is connected to the roadside control cabinet by wire to detect the slotting area of ​​the coil Usually it is 1.2*0.8 meters, and the length of the communication trunking can reach hundreds of meters, so it has complex construction, expensive labor, and time-consuming. It takes an aver...
